Solving for X on Both Sides

Solve: 4x - 3 = 6x - 19

• x = -8

• x = 11

• x = -11

• x = 8

Solve: 12x + 1 = 6x - 47

• x = 6

• x = -7

• x = -8

• x = 9

Solve: 3x + 16 = 7x + 64

• x = 10

• x = -10

• x = -11

• x = -12

Solve: -3x + 20 = 2x - 40

• x = 15

• x = 12

• x = -15

• x = -12

Solve:
7x = 3x + 24

• 6

• 10

• 14

• 4

Solve for x:
4(1-x) + 3x = -2(x+1)

• x = -6

• x = 6

• x = 3

What operation did he perform to get from Step 1 to Step 2?

• Subtracted 2x from both sides of the equation

• Subtracted 9 from both sides of the equation

• Multiplied both sides of the equation by 3

• Added -3 to both sides of the equation

What is the error?

• Adding 2x to 3x

• Subtracting 5 from both sides

• Adding 2x to -2x

• Dividing by 5 on both sides

54x + 64 ≥ 49x + 59

• x≥−1

• x≤-1

• x>9

• x<-3

Solve:
11x + 16 < 43 + 2x

• x < 5

• x < 3

• x > 5

• x > 3
